Chapter 971 Very Simple Model
Qi Younian knew that it was very hard for Ye Xinyan to manage and even expand Guangsha Construction without a competent helper.But he didn't think that Ye Xinyan was not familiar with construction.

The old man smiled and said: "It's really hard for Ye Zi. But, who said you are not familiar with the construction business? My old man was the first to refuse to slander my Ye Zi like this. It has only been more than two months, not only the business of the construction business has expanded, but also the personnel. It has expanded a lot, and it is more sufficient than the previous manpower.

Not only won this year's project, but even booked in advance for next year's project.Don't say you are a girl who has only been in the construction industry for a few years, even your grandpa Zhang and I have been working as craftsmen for decades, and you can't do better than you. "

Everyone laughed and echoed, they all recognized and admired from the bottom of their hearts.If you are not good at building things based on what grandma does, then no one present will dare to claim to be good at it.

Qi Younian is really satisfied with Ye Xinyan's affairs during this period, "Okay. From tomorrow on, you can just take a break. When you have a rest, you can come back to work. If you can't get enough rest, then just keep resting. See grandpa making money for you, you just have to wait at home to collect the bill."

Everyone burst into laughter.

Jiang Yifan said with a smile: "That's impossible, she just wanted to avoid laziness. Grandpa is exhausted, so he has to rest for a while. It's impossible for you to be busy when you come back, but let the younger generation sit at home and enjoy the benefits." reason?"

Ye Xinyan quickly responded: "That's right, that's right, Grandpa, you should rest for a few days first. I'll rest when you're done." Lazyness is a must, and it's okay to start a few days later.

Yuan Shang chatted with Qi Younian for a while yesterday, and knew more things than Ye Xinyan. At this moment, he also smiled and said: "It's better for Grandma to rest first. When Grandma Bi Yao comes back, Grandma will work with her again. Then When the grandma is doing things, someone will accompany her."

"Oh? Is Baguio coming back?" Ye Xinyan really didn't know about it.

Qi Younian said with a smile: "I didn't have time to tell you yesterday that the abbot of a temple we built put forward some requirements on the structure of a main hall, and refused to allow the use of iron nails. I will find Aqiao to discuss the structure of the tenon and tenon. .

Aqiao said that the machine he and Shi Yin made could work after it was fired with charcoal.He brought you back the blueprints. If the structure works, he and Mr. Shi will return to Beijing with the relocated mechanical workshop in the spring of next year.After a while you take the blueprint to have a look, it’s very complicated, I spent a lot of effort, but I didn’t understand what it was. "

"Huh? A steam engine? So fast?" Ye Xinyan's eyes widened instantly, very excited.

Yuan Shang said: "I was also surprised when I heard it yesterday. Burning charcoal can make the iron guy move. It sounds weird. I listened, and I wanted to see what it was one day. I can't wait until the spring of next year." gone."

…………

At noon, everyone ate a grand meal together, and even Guan He, who was impatient to socialize, joined everyone to help eliminate all kinds of dishes that were served in the flowing water.

Qi Younian, Guan He, Jiang Yifan and others also had a few drinks.

In the afternoon when everyone dispersed, Ye Xinyan and Jiang Yifan stayed behind, together with Qi Sanshun and Qi Jiaer, talking and chatting with Qi Younian.

The Qi family was busy these two days, and Ye Yuan lived in Zi Ning and Guan He's side courtyard again.

Zi Ning has been pregnant for seven months, and she likes children even more. Not only does she not think it is tiring to take care of children, but she is willing to let him stay for a few more days.

Ye Yuan frequented the Qi family, and was also very familiar with Qi Younian. He followed Qi Jiaer and called him Grandpa Qi Younian, and the two were very close.

This time I haven't seen Qi Younian for more than two months. When we saw each other again, it was so rare that even Ye Xinyan stood aside and sat in Qi Younian's arms for a long time, listening to everyone talking.It wasn't until she yawned that she was coaxed by Zi Ning and went back to take a nap.

In the evening, my family had dinner together again, and Ye Xinyan returned to her home with the drawings brought back by Qi Younian.

Wang Qiao's diagram can only be regarded as a simple steam engine model diagram, similar to the kind that students do by hand in professional schools.

Even so, it is already a milestone progress for an ancient man to convert heat energy into mechanical energy.

With this basic tool, if there is no official resistance, various technologies such as smelting and forging will inevitably be promoted.Using better steel, increasing steam pressure and power, and gradually improving sealing and rotation wear, steam engines can be applied in all aspects.

Although this model is only equivalent to the experimental assignments assigned to students by professional schools, the drawings are not simple at all, and can even be called very complicated.For those who have not been in contact with it, it is also difficult to understand its structure and principle.

Jiang Yifan is now working in the Ministry of Industry, and he is very interested in this kind of tools and utensils.

The two went back and changed their clothes, lit a few candles, spread out the drawings, and leaned side by side on the table to watch them carefully.

Ye Xinyan was born in science and engineering. After working, she also came into contact with these things, so of course she can understand them.

The steam engine model made by Wang Qiao and Shi Yin, from the blueprint alone, is completely correct in structure and principle, basically considered a success.Just wait to perfect the details in the process of using it.

While looking at it, she pointed to each part of the drawing and explained it to Jiang Yifan bit by bit.

Ye Xinyan thought she had explained it in a very simple way, but Jiang Yifan still couldn't understand it.Without manpower, there is nothing. How can it be possible to move iron objects with only charcoal to boil water?

Really helpless, Ye Xinyan found paste and thick paper, according to Wang Qiao's drawings, simply made a few paper tubes, round paper, and then glued toothpicks and other things to replace the connecting rod and transmission parts, combined Slowly gesture to Jiang Yifan for the rise of steam when boiling water.

After several movements, Jiang Yifan gradually had some understanding.After understanding it, it was hard to conceal the shock, "You said that this kind of thing can generate a lot of power, how much power can it have?"

"Where is the biggest?" Ye Xinyan smiled. She has no chance to touch the biggest power similar to aerospace, so she can only say, "As long as the material used to make the steam engine is strong enough, the power it can generate can be infinite."

"The earliest evaluation of the power of this kind of thing is horsepower, which you can understand as the power of a horse. Later, things similar to steam engines have been popularized in civilian use, and a machine can easily have tens of thousands of horsepower. You can Imagine that in a not-so-big room, there are one or even a few machines with hundreds or thousands of horsepower rumbling."

Thousands of horsepower?A little excited, Jiang Yifan focused his eyes on the blueprint again, and looked at it carefully.

Comparing Ye Xinyan's paper model, he seemed to understand a little bit, and asked with some longing: "Ayan, can this thing be widely used here?"

Ye Xinyan didn't give him hope, she just shook her head and said: "Machine needs various craftsmen and investment, and it needs to be continuously improved and perfected over the years. In the process of finding shortcomings, it is necessary to continuously develop and improve other related industries. Including materials and application industries, etc. Such uninterrupted efforts can only make substantial progress after more than ten years or decades."

She looked at Jiang Yifan's slightly disappointed face, and continued: "As for the widespread application among the people, I'm afraid it will take hundreds of years, and it will take longer time and perseverance to make continuous improvements."

This is also where Ye Xinyan is most uncertain.

"Uninterrupted?" Jiang Yifan was thoughtful.Uninterrupted, and uninterrupted for decades, or even hundreds of years.Involving the subsequent throne and even the change of dynasties, it is just a matter related to craftsmen, can it be uninterrupted?
